Hereinafter, a remote control system according to a second embodiment of the present invention will be described with reference to FIG. The remote control system of the present embodiment has substantially the same configuration as that of the first embodiment, and various terminal devices in the home are network-connected to one parent device 9 by wireless, and the parent device 9 and the various terminal devices 2, Signals are exchanged between 3, 4, 5, 6, 7, and 8.

  The base unit 9 is connected to an external server 17 outside the home via the Internet 16 and is configured to be accessible from a mobile phone 18 to the external server 17. Based on the operation signal transmitted from the mobile phone 18, the external server 17 converts the control signal into a control signal including control operation contents of various terminal devices set in advance corresponding to the signal, and converts the control signal to the control signal. Transmit to the base unit 9.

  In this embodiment, unlike the first embodiment, each terminal device is provided with an infrared light receiving device 2a (only shown for the bedroom lighting device 2), and the mobile phone 18 is provided with an infrared light emitting device 18a. It is done. The infrared light receiving device 2a of each terminal device may be also used as an infrared light receiving device emitted from an operation remote controller of each terminal device itself.

  In addition, each terminal device transmits a radio signal (current position signal of the mobile phone) to the base unit 9 via the network connection with the base unit 9 when the light receiving device 2a receives infrared rays from the mobile phone 18. Configured to do. The base unit 9 is configured to recognize the current position of the mobile phone 18 (the room where the user is present) by receiving the radio signal.

  In the system 1 of the present embodiment, for example, as illustrated in FIG. 5, when the user turns on the lighting device 2 with the mobile phone 18 in the bedroom, the user operates as follows. Thus, the lighting device 2 in the bedroom can be turned on.

  Before accessing the external server 17, the user first transmits infrared rays toward the lighting apparatus 2 using the mobile phone 18. The luminaire 2 that has received the infrared rays transmits a wireless signal (current position signal of the mobile phone) to the parent device 9. The wireless signal includes the ID (identification information) of the lighting fixture 2 itself, and the master unit 9 that has received the wireless signal identifies the current position of the mobile phone 18.

  Next, the user accesses the external server 17 using the mobile phone 18 and inputs an operation signal for lighting the lighting fixture 2. The operation signal is converted into a predetermined control signal by the external server 17 and transmitted to the parent device 9. At this time, the user does not need to input information for designating the terminal device to be operated, and only needs to input information for instructing “lighting” as the operation content.

  At this time, the control signal transmitted from the external server 17 to the base unit 9 is a signal having the same configuration as the signal shown in FIG. 3, and the address information written in the header section 19a is transmitted with the default value. Is done.

  The base unit 9 that has received the control signal has already identified the current position of the mobile phone 18 and has information on the installation position of each terminal device in the microcomputer 9b in advance. A control signal for instructing lighting is transmitted toward the lighting fixture 2 in the bedroom in the vicinity. And the lighting fixture 2 of the bedroom which received this control signal lights.

  When a plurality of lighting fixtures are generally installed in one room like the lighting fixture 2, based on the current position of the mobile phone 18 identified by the master unit 9, There is no problem if a control signal is transmitted to the luminaire 2 (in the room where the user is present) and a plurality of luminaires are turned on or off at the same time. For example, the center room on the second floor shown in FIG. When the lighting fixture 2 and the air conditioner 3 are installed in one room and it is necessary to operate one of the devices, the user uses the mobile phone 18 to send an operation signal. When inputting, information for distinguishing terminal devices in the same room is input.

  Even in this case, the information for distinguishing the terminal device to be input by the user may be information that can distinguish a small number of terminal devices in the same room (near the current position of the mobile phone 18). Unlike the information for distinguishing all the terminal devices in the home in the remote control system of FIG.

  In addition, as shown in FIG. 6, instead of the infrared light receiving device attached to each terminal device, radio waves from the mobile phone 18 can be received. A radio wave transmitting / receiving device 21 that transmits radio wave information indicating that a radio wave has been received from the telephone 18 may be installed in each room and important point.

  In this case, before accessing the external server 17, the user first transmits a radio wave for specifying the position to the radio wave transmitter / receiver 21 using the mobile phone 18. The radio wave transmitter / receiver 21 that has received the radio wave transmits a radio signal (current position signal of the mobile phone 18) to the base unit 9. The wireless signal includes the ID (identification information) of the wireless transmission / reception device 21, and the base unit 9 that has received the wireless signal receives the current position (user) of the mobile phone 18 from the ID (identification information) of the wireless transmission / reception device 21. Identify the room in which there is. Accordingly, a control signal that is subsequently input from the external server 17 to the base unit 9 is transmitted by the base unit 9 to a terminal device in the vicinity of the current position of the mobile phone 18 (the room where the user is located).

  Furthermore, as another modification, the mobile phone has a function of acquiring position information from a GPS (Global Positioning System) satellite, and the radio wave transmission / reception device 21 can be omitted.

  Specifically, as shown in FIG. 7, when the user uses the mobile phone 18, the mobile phone 18 acquires the location information of the mobile phone 18 itself from the GPS satellite 22, and uses the acquired location information as a parent. To the machine 9. Receiving this position information, base unit 9 identifies the current position of mobile phone 18. Accordingly, a control signal that is subsequently input from the external server 17 to the base unit 9 is transmitted by the base unit 9 to a terminal device near the current position of the mobile phone 18.

  In the remote control system 1 shown in FIG. 5 and FIG. 6, the terminal device receiving the infrared ray transmitted from the mobile phone 18 transmits the radio to the base unit 9, and the ID (identification information) of the own terminal device. ) And a step of transmitting the ID (identification information) of the own radio wave transmitter / receiver 21 by transmitting the radio wave of the radio wave transmitter / receiver 21 received from the mobile phone 18 to the base unit 9. Any of these can be transformed into a process via the mobile phone 18 as follows.

  That is, in the case of the remote control system 1 shown in FIG. 5, for example, the luminaire 2 that receives infrared rays transmitted from the mobile phone 18 does not wirelessly transmit to the base unit 9 but to the mobile phone 18. Then, an infrared signal including the ID (identification information) of the own lighting fixture 2 is returned, and the mobile phone 18 that has received the signal returns a signal including the ID (identification information) of the lighting fixture 2 to the base unit 9 wirelessly. Send. In this case, each terminal device is provided with an infrared light emitting device, and the mobile phone 18 is provided with an infrared light receiving device.

  In the case of the remote control system 1 shown in FIG. 6, the radio wave transmitting / receiving device 21 that has received the radio wave transmitted from the mobile phone 18 does not wirelessly transmit to the base unit 9, but to the mobile phone 18. A signal including the ID (identification information) of the own radio transmission / reception device 21 is returned, and the mobile phone 18 that has received the signal wirelessly transmits the signal including the ID (identification information) of the radio transmission / reception device 21 to the base unit 9. Send.

  As described above, in the remote control system 1 of the present embodiment, since the base unit 9 can identify the current position of the mobile phone 18, the user can select the operation target included in the operation signal input using the mobile phone 18. The information on the terminal device to be used can be omitted, which is convenient and convenient for the user, and can prevent troubles such as operating an incorrect terminal device (a terminal device in another room).

(Third embodiment)
Hereinafter, a remote control system 1 according to a third embodiment of the present invention will be described with reference to FIG. The remote control system of the present embodiment has substantially the same configuration as that of the first embodiment, and various terminal devices 2, 3, 4, 5, 6, 7, 8 in the home are wirelessly connected to one master unit 9. Connected to the network, signals are exchanged between the base unit 9 and various terminal devices.

  The base unit 9 is connected to an external server 17 outside the home via the Internet, and is configured to be accessible from a mobile phone 18 to the external server 17. Based on the operation signal transmitted from the mobile phone 18, the external server 17 converts the control signal into a control signal including control operation contents of various terminal devices set in advance corresponding to the signal, and converts the control signal to the control signal. Transmit to the base unit 9.

  And in this embodiment, while being comprised so that time information can be included in the operation signal transmitted to the external server 17 from the mobile telephone 18, the external server 17 is sent with respect to the main | base station 9 based on the said time information. Thus, a function of transmitting a control signal for controlling the terminal device at an appropriate time is added.

  In the system 1 of the present embodiment, when the time information is included in the operation signal transmitted from the mobile phone 18 to the external server 17, the external server 17 that has received the operation signal operates the master device 9. The target terminal device transmits a control signal so that the operation is completed at the time indicated by the time information included in the operation signal. With this function, the desired terminal device completes its operation at the time input by the user (such as the time to go home), so that there is an advantage that no unnecessary waiting time or the like occurs for the user.

  Specifically, for example, when the user inputs the operation content for turning on the lighting device 2 in the bedroom using the mobile phone 18 and enters the return time (for example, 20:00), the external server 17 receives the received operation. Based on the signal, a control signal for turning on the lighting device 2 in the bedroom is transmitted to the parent device 9, and the lighting device 2 in the bedroom is turned on through the parent device 9. Thereafter, when the external server 17 detects that the return time (20:00) has arrived by the built-in timer, the external server 17 transmits a control signal for turning off the lighting device 2 in the bedroom to the master unit 9, and The lighting fixture 2 is turned off.

  By the above control, the lighting device 2 in the bedroom is turned on while the user is away and is turned off when the user returns home. Therefore, the bedroom lighting device 2 is effective for crime prevention by pretending to be home, and the lighting of the bedroom after the user returns home. Even if the user forgets to turn off the fixture 2, the lighting fixture 2 will not continue to be turned on unnecessarily, thus saving energy.

  Similarly, for the purpose of crime prevention, it is possible to control the front lighting device (security light) 7 so that it is lit brighter while the user is away and returns to normal brightness when the user returns home.

  Further, for example, when this function is used in a fully automatic washing machine, the operation can be performed as follows while the user is away.

  For example, when the time required for washing by the fully automatic washing machine 23 shown in FIG. 8 is 1 hour, the user accesses the external server 17 using the mobile phone 18 and sets the required time (1 hour) in advance to the outside. It is stored in the server 17. After that, when the user inputs the operation content for operating the fully automatic washing machine 23 using the mobile phone 18 and inputs the return time (for example, 20:00), the external server 17 is one hour from the return time (laundry). When the time (19:00) before the required time) arrives, a control signal is transmitted to the master unit 9 so that the operation of the fully automatic washing machine 23 starts, and the fully automatic washing machine 23 starts washing. Therefore, when the user returns home when the laundry is completed after one hour, the laundry is completed, and the user can immediately take out the washed clothes and start the next operation such as a drying operation. Similarly, it is possible to perform control so that the food in the refrigerator 24 is thawed in accordance with the return time.

  The present invention is not limited to the configuration of the above embodiment, and various modifications can be made. For example, the parent device may be one in which a microcomputer is mounted on a centralized switch device used in a home network system.
